After having some time to think about it. The only reason why it’s not really designed for this feature request is because the Sample Editor is mainly reliant on the “Event Start” and “Event End” points while having a reference to the full audio file behind it. Having to ability to re-arrange Audio Events within the Sample Editor would break this link.
The idea was good until I thought about that. But be honest, how many times have you done some tasks within the Sample Editor only to have to re-adjust all of the zoom and quantization settings in the Project Window afterwards ?
I’ve already made a feature request about how the Sample Editor and Audio Part Editor could be integrated slightly better here: Sample Editor - Add setting to "Open Audio Part Editor Automatically" after creating Hitpoint slices
